3 Functions and featuresPressure Equipment Directive (PED): The units comply with section 3, article (3) of the Directive 97/23/EC and must be designed and manufactured for non-super-heated liquids of group 1 fluids in accordance with the sound engineering practice�The unit monitors liquid media�The unit detects the 3 process categories volumetric flow quantity, consumed quantity and medium temperature�Application areaConductive liquids with the following properties:• Conductivity:≥20µS/cm• Viscosity: < 70 mm2/s at 40°C
4 Function4.1 Measuring principle for volumetric flow monitoringThe magnetic-inductive measuring principle means that a magnetic field is gener-ated in the measuring pipe via current-carrying coils� When a conductive medium flows through the measuring pipe, the ions therein are diverted perpendicularly to the magnetic field� Positive and negative charge carriers flow in opposite direc-tions� The voltage induced is measured by two electrodes that are in contact with the medium� This signal voltage is directly proportional to the average flow veloc-ity� The volumetric flow quantity is derived from the internal pipe diameter�

Both electrodes must be wetted by the medium� Otherwise the signal [SEnS] for empty pipe is provided, if empty pipe detection is enabled�
4.2 Processing of the measured signalsThe unit displays the current process values�It generates 2 output signals according to the parameter setting�
OUT1/IO-Link: Parameter setting - Analogue signal for volumetric flow quantity (→10.3) - Communication interface (→10.6.5)
OUT2: Parameter setting - Analogue signal for temperature (→10.4)
4.3 Flow rate measurementAn analogue signal which is proportional to the volumetric flow (4���20 mA) is pro-vided on output 1 in case of medium flow in the measuring pipe� (On the analogue functions→4.7)In addition to the flow velocity, the unit also detects the flow direction� An arrow on the unit indicates the positive flow direction� Theflowdirectioncanbeinversed(→10.5.4).
► Use the supplied label to mark the changed flow direction�
Direction of flow corresponds to "flow direction" > process value and display positive�Direction of flow against "flow direction" > process value and display negative�
Only positive process values are processed for the signal output�
4.4 Consumed quantity meterThe unit has an internal mass flow meter which continuously totals the volumetric flow quantity� The total corresponds to the current consumed quantity�• The quantity meter takes account of the flow direction for totalisation:
![Page 8: Operating instructions Magnetic-inductive flow …8 2 Main menu, Extended functions 16 8 3 Basic ... The magnetic-inductive measuring principle means that a magnetic field is gener-ated](https://reader034.vdocument.in/reader034/viewer/2022043009/5f9d41b49959d25f28063c37/html5/thumbnails/8.jpg)

- Flow according to the marked flow direction (arrow "flow direction"): meter adds�
- Flow against the marked flow direction: meter subtracts�The meter saves the totalled consumed quantity every 10 minutes� After a power failure this value is available as the current meter reading� So the possible data loss can be maximum 10 minutes�The current meter reading can be evaluated via an external parameter setting software(→10.6.5ActivatingtheIO-Linkcommunicationinterface).
4.5 Temperature monitoringAn analogue signal (4���20 mA) can be provided on output 2 for temperature moni-toring.Ontheanaloguefunctions→4.7).
